Call of Duty: World at War was another World War II game.
I know, everytime I say I’m done with World War II as a setting, they come out with another WWII game and I pick it up. This one, I picked up because it was on sale, and it has a cooperative game mode wherein you fight an unending horde of zombies until you are overwhelmed.
There is no “winning” this mode. Eventually the undead will outnumber you and you can’t hold them back any longer.
